Bike It Pressure Alert Valve Cap 41-43 PSI Range

Simple but effective valve caps the constantly monitor tyre pressure and alert you of pressure loss. Each cap has a minimum pressure rating, when tyre pressure is above the minimum a green ring shows – all OK. If pressure drops below the minimum rating, a red ring shows – time to inflate and check tyres. Select the lowest P.S.I. limit nearest to the bike manufacturer’s recommended tyre pressure.
